[0027] For example, Figure 7 and Figure 8As shown, the protective cutting mechanism 9 includes a protective box 901; a cutting machine 902 is provided on the inner wall of one side of the protective box 901; a cutting wheel 903 is transmission-connected to the output end of the cutting machine 902; a first telescopic slot 907 is provided at the bottom of the protective box 901; two groups of sealing plates 904 are symmetrically and movably penetrated at the bottom of the first telescopic slot 907; each group of sealing plates 904 is U-shaped in cross-section when viewed from above; a number of groups of gas springs 908 are evenly spaced on the top inner wall of the first telescopic slot 907; the other end of each group of gas springs 908 is connected to a corresponding group of sealing plates 904; two groups of second telescopic slots are symmetrically provided on the top inner wall of the first telescopic slot 907 909; a group of telescopic plates 905 are movably penetrated at the bottom of each group of the second telescopic slots 909; both side walls of each group of the telescopic plates 905 are movably fitted on one side wall of a corresponding group of sealing plates 904; two groups of third motors 910 are symmetrically arranged at the two side edges of the top of the protective box 901; the output end of each group of the third motors 910 is penetrated into the corresponding group of the second telescopic slots 909, and is transmission-connected with a group of third screw rods 911; each group of the third screw rods 911 is threadedly connected with the corresponding group of telescopic plates 905; the bottoms of the two groups of telescopic plates 905 are transmission-connected with a sealing pressure assembly 906; the sealing pressure assembly 906 movably penetrates the limiting slot 402.

[0029] When cutting metal pipe raw materials, the metal pipe raw materials are placed in the limiting grooves 402 of several groups of raw material limiting mechanisms 4. After adjusting the spacing of several groups of raw material limiting mechanisms 4 according to the size of doors and windows, several groups of second electric push rods 412 are controlled to drive several groups of clamping plates 413 to clamp and limit the metal pipe raw materials, and then several groups of protective cutting mechanisms 9 are controlled to descend to perform multi-point synchronous cutting on the corresponding parts of the metal pipe raw materials. During the cutting process, the protective box 901 drives the cutting machine 902 and the cutting wheel 903 to descend to cut the metal pipe raw materials. At the same time, the two groups of sealing plates 904 gradually shrink into the first telescopic groove 907, so that the cutting wheel is always in a closed state before and after the cutting process, avoiding the risk of accidental touch by personnel and improving the safety of the cutting device. When cutting, the protective box 901 drives the cutting machine 902 and the cutting wheel 903 to descend to cut the metal pipe raw material. At the same time, the two groups of third motors 910 drive the two groups of third screw rods 911 to rotate. Under the threaded connection relationship between the two groups of third screw rods 911 and the two groups of telescopic plates 905, the two groups of telescopic plates 905 drive the sealing pressure assembly 906 to rise. At the same time, the protective box 901 maintains its position unchanged during the descent process, so that the sealing connecting plate 9062 maintains its position unchanged in the cutting groove 403, so that the cutting wheel can cut the metal pipe raw material after cutting the through groove 9063. At the same time, the induced draft fan 411 is started to blow the metal debris in the cutting groove 403 into the dust collecting chamber 12 through the dust collecting groove 3 and fall into the dust collecting box for collection. This not only avoids the metal debris generated during cutting from floating into the air, but also allows the metal debris to be collected for convenient centralized treatment. Before cutting the metal pipe raw materials, several groups of metal pipe raw materials are placed on the top of several groups of support rollers 404 in the limiting grooves 402 of several groups of raw material limiting mechanisms 4, and then several groups of second motors 407 are controlled to drive several groups of second screw rods 408 to rotate. Under the threaded connection relationship between several groups of second screw rods 408 and several groups of sliding support plates 409, several groups of sliding support plates 409 drive several groups of straightening rollers 405 to clamp on the two side walls of the metal pipe raw materials through corresponding transmission plates 410, and then several groups of sealing pressure components 906 are controlled to apply corresponding pressure to the top of the metal pipe raw materials, and pressure is applied to the metal pipe raw materials in four directions through several groups of support rollers 404, straightening rollers 405 and pressure rollers 9065, and then several groups of raw material limiting mechanisms 4 are controlled to reciprocate horizontally, so that metal pipe raw materials of different sizes can be straightened, which not only improves the convenience of use of the cutting device, but also improves the processing quality of the cutting device.

[0030] By controlling several groups of transmission blocks 14 to drive several groups of raw material limiting mechanisms 4 to fix the corresponding parts of the metal pipe raw materials according to the sizes of doors and windows, several groups of transmission blocks 14 will also drive several groups of protective cutting mechanisms 9 to move synchronously through the corresponding support plates 7 and the first electric push rods 8, and then control several groups of first electric push rods 8 to drive several groups of protective cutting mechanisms 9 to descend to perform multi-point synchronous cutting of the metal pipe raw materials, which not only avoids the need for manual measurement of dimensions for cutting, but also enables cutting work to be performed synchronously at multiple points, thereby improving the processing convenience of the cutting device while also improving the processing efficiency.

[0031] By controlling a plurality of groups of straightening rollers 405 to clamp the two side walls of the metal tube raw material, and then controlling a plurality of groups of sealing pressure components 906 to apply corresponding pressure to the top of the metal tube raw material, pressure is applied to the metal tube raw material in four directions through a plurality of groups of supporting rollers 404, straightening rollers 405 and pressure rollers 9065, and then controlling a plurality of groups of raw material limiting mechanisms 4 to reciprocate horizontally, metal tube raw materials of different sizes can be straightened, which not only improves the convenience of use of the cutting device, but also improves the processing quality of the cutting device.

[0032] By controlling the sealing pressure assembly 906 to maintain a constant position during the descent of the protective box 901, the sealing connecting plate 9062 maintains a constant position in the cutting groove 403, so that the cutting wheel can cut the metal pipe raw material after cutting the through groove 9063. At the same time, the induced draft fan 411 is started to blow the metal debris in the cutting groove 403 into the dust collecting chamber 12 through the dust collecting groove 3 and fall into the dust collecting box for collection. This not only prevents the metal debris generated during cutting from floating into the air, but also allows the metal debris to be collected for convenient centralized treatment.

[0033] By controlling several groups of clamping plates 413 to clamp and limit the metal pipe raw material, and then controlling several groups of protective cutting mechanisms 9 to descend, the corresponding parts of the metal pipe raw material are cut synchronously at multiple points. During the cutting process, the protective box 901 drives the cutting machine 902 and the cutting wheel 903 to descend to cut the metal pipe raw material. At the same time, the two groups of sealing plates 904 gradually shrink into the first telescopic groove 907, so that before and after the cutting process, the cutting wheel is always in a closed state, avoiding the risk of accidental touch by personnel and improving the safety of the cutting device.
